Hydride heat pump with heat regenerator

Patent ·
OSTI ID:5554740
This patent describes a regenerative temperature hydride heat pump process for cooling a chamber. It comprises confining a first hydride in a plurality of first reaction zones and maintaining the temperature thereof in a first temperature range, the number of first reaction zones being at least four; introducing hydrogen gas from a source of hydrogen gas into a predetermined one of the first reaction zones and sorbing the hydrogen gas on the first hydride therein; desorbing hydrogen gas from the first hydride in another predetermined one of the first reaction zones and removing the desorbed hydrogen gas therefrom; transferring heat between the first reaction zones by circulating a first heat transfer fluid in series flow around a loop of the first reaction zones, thereby regenerating heat, while preventing the first heat transfer fluid from directly contacting the first hydride; transferring heat from the predetermined one of the first reaction zones recited in step (b) to the environment; transferring heat from a chamber to the another predetermined one of the first reaction zones recited in step (c) thereby aiding the desorption of the first hydride therein; confining a second hydride in a plurality of second reaction zones and maintaining the temperatures thereof in a second temperature range which is higher than the first temperature range recited in step (a), the number of second reaction zones being equal to the number of first reaction zones.
